Be more specific. What do you mean by "open"? Does the manifold gasket leak, is the manifold cracked, is the air filter or air filter hose not connected? What are the symptoms, and who told you it was open?

The intake code means its leaking from the intake,bad gaskets, or a vacuum leak. check for bad gaskets on intake manifold. You can tell by putting a bit of oil around the maifold. if it is leaking the engine will flair up. To check this, External leak-- Coolant seeps through the broken intake manifold gasket to the outside of the engine. If its bad enough you will see coolant dripping from gasket. Coolant seeps through the damaged gasket to the inside of the engine, mixing with motor oil. If you suspect an internal leak, check your oil dipstick. Or if you have a substance under oil filler cap that looks like a milkshake, Oil is mixing with coolant. this means intake gaskets are bad, Now for the camshaft sensor, If you have a manifold leak. this could be giving you a false camshaft reading! Because, If sensor is bad vehicle will not start unless theres a wire problem. Symtoms of a bad sensor are--- engine sputtering, poor acceleration, stalling/inability to start. HopeI helped you out! Good-Day!

sounds like you have to do a cable adjustment.
if you have two people one of the easiest ways to do this is have someone inside the drivers sine press the gas pedal all the way to the floor.
Loosen up all the hold down cable connectors near the throttle body.
Re position cable tauntness so the valve body is open full and not a pinch more.
Tighten everything in place then release gas pedal.
you should have enough play in the cable for the sensors to register zero.
now clear the code should be no more problem, works on just about any car that has fuel injection.
